Just working on SVG export. There are more ways how to handle labels --
but no perfect one.
1) Use SVG fonts (embedded). These would be supplied with Therion
(converted from TeX fonts used in PDF output).
pros: the SVG map will be nearly identical to PDF
cons: large file (fonts are embedded)
SVG fonts are unhinted
hard to edit in drawing programs
hard to add new font
2) Use system fonts
pros: small file (fonts are not embedded)
full unicode support (if unicode fonts are installed)
cons: platform dependent
problems with precise alignment of labels
metapost can't calculate frames (e.g. for passage height) nor
3) Use system fonts but supply font metrics for metapost
pros: nice output with clipping paths, alignment etc.
hard to generate metrics for the regular user
4) Use bitmaps as labels
would require additional convertor
I'd like to get your comments, hints or suggestions, which one to prefer.
I'd say the 1st one.
